Founded in 1989 as Urayasu Junior Football Club, the team was established in Chiba Prefecture.

The name refers to a mix composed by Brionac, a spear appeared in Celtic mythology, and Becca, a one-seater ship used to collect nori, a Japanese cuisine delicacy, typical of that region.

Their performance at the competition qualified the club to the 2022 Japanese Regional Football Champions League.

On the same year, the club recorded their worst performance at the Kanto League since their JFL relegation on 2017.
